## What is Clipaper?

Clipaper is an iPhone and iPad workspace for reading PDFs, writing notes, and keeping important research material in view.

Add papers and documents to your library and annotate them directly with Apple Pencil. Clip an equation or table to the reference board so it stays visible while you move between pages. Clipaper can also suggest equation and table candidates found in a PDF.

Key features

• PDF library
PDFs you open are saved in the app, ready whenever you return.

• Apple Pencil annotation
Write with pens and highlighters, erase, select with the lasso, and use shape recognition in PDFs and notebooks.

• Reference board
Clip and pin equations or tables from a PDF, or choose from automatically detected candidates. Jump from a clip back to its source page.

• Search and outline
Find text in a PDF and jump to a page from the table of contents.

• Library organization
Sort papers and notebooks with folders, tags, and keyword search.

• PDF and notebook side by side
Read and write in the same view. Scanned PDFs can use OCR to suggest equations and tables.

• Flexible notebooks
Choose blank, ruled, or dotted pages. Combine white, dark gray, or yellow paper with portrait or landscape pages, single-page or continuous display, and vertical or horizontal scrolling.

• Natural navigation
Swipe between individual pages, scroll continuously, and pinch to zoom around the content currently in view.

• Laser pointer
Highlight an area with a temporary trail while explaining or presenting.

• PDF export
Export annotated documents and complete notebooks as PDF for sharing with other apps.

• iCloud sync
When iCloud is available, Clipaper syncs PDFs, notebooks, handwriting, and reference clips across devices. Work is saved locally while offline and sync is retried after reconnecting.

• Move from Goodnotes
Export a notebook as PDF from Goodnotes, then add that PDF to Clipaper.

No separate Clipaper account is required. Keep reading, writing, and organizing in one focused research and study space.
